The importance of this component is even more evident in the fact that the most important invention of ''Lewis Edson Waterman'', the one that leads many to consider him (with some exaggeration) the father of the fountain pen, is related to the construction of the feeder. Of course, well before concentrating on [[materials]] and [[loading systems]] at the end of the 1800s, manufacturers were competing (and investing their research efforts) on this very element, which characterized their pens (think, for example, of [[Parker]] ''[[Lucky Curve]]'' or [[Waterman]] ''[[Spoon feed]]'') since a well-functioning feeder was then what could lead to success or failure.

E benché in seguito il rilievo dell'alimentatore, almeno nel materiale promozionale, sia diminuito a scapito di altre parti e caratteristiche tecniche (e soprattutto rispetto a quelle stilistiche) esso resta comunque una delle parti essenziali del funzionamento di una stilografica, ripreso in più casi dai produttori (come per il ''[[Magic Feed]]'' della [[Eversharp]] o il ''[[tintomatic]]'' della [[Lamy]]).  

And although later on the importance of the feeder, at least in the promotional material, has decreased at the expense of other parts and technical characteristics (and especially compared to the stylistic ones), it is still one of the essential parts of the functioning of a fountain pen, taken up in several cases by the manufacturers (as for the [[Eversharp]] ''[[Magic Feed]]'' or the [[Lamy]] ''[[tintomatic]]'').  

A parte le costruzioni ancora molto primitive presenti fino ai primi anni del 1900, che prevedevano ancora per alcune aziende (come [[Swan]] e [[Onoto]]) la presenza del cosiddetto [[alimentatore superiore]] la forma canonica dell'alimentatore come elemento posto al di sotto del pennino si è andata sviluppando in maniera abbastanza rapida.
